Title:
REINFORCED THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2012201811
Kind Code:
A
Abstract:

To provide a reinforced thermoplastic resin composition capable of providing a molded product in which deterioration of rigidity upon humidity adsorption is reduced, moreover, which has excellent shock resistance and heat resistance when a high load is applied and which is excellent also in designability upon coating.

The reinforced thermoplastic resin composition includes: a graft copolymer (A) prepared by graft-polymerizating 25 to 60 pts.mass of monomer mixture which includes 60 to 95 mass% of vinyl aromatic monomer (b) and 5 to 40 mass% of vinyl cyanate monomer (c) in the presence of 40 to 75 pts.mass of rubbery polymer (a); a maleimide based copolymer (B) prepared by copolymerizing 5 to 50 mass% of maleimide based monomer (d) and 50 to 95 mass% of other monomer copolymerizable with the maleimide based monomer (d); a polyamide resin (C) having a relative viscosity of 1.8 to 3.0; a compatibilizer (D); and inorganic filler (E), in specific amounts.
